Letters Patent No. 99,852, dated February 15, 1870.

The Schedule referred .to in theseLetters Patent and making part of the same.

To all whom it lmay concern Be it known that I, RICHARD D. COX, of the city and county of Philadelphia. and State of Pennsylvania, have invented certain Improvements in Brick-Kilns; and I do herebydeclare that the following is a full, clear, and exact description thereof, reference -heing had to the annexed drawings, making part of this specification, in which- Figure l is a horizontal section.

Figure 2 is a vertical section.

Figure?) is an end elevation.

The same letters are used in all the figures to designate identical parts.

My invention relates to the combination 4and ar-v rangement of the parts forming a cont-inuous kiln, as will be hereinafter set forth in the following specification and claims.

A is a permanent wall forming a rectangular kiln. It is subdivided into compartments B B by permanent pigeon-holed walls b uilt on each 'side of the cumbustion-chambers G, which` areplaced between the compartments, except at the ends, where they are placed between the compartments and the solid end walls.

The compartments may be entered by doors B2 B2, and they may, if for any purpose so desired, be divided by cioss-walls B1.

The combustion-chambers extend entirely across the kiln and havedoors C' C placed at each end, and extend upward to the top of the kiln.

The pigeon-holes in the walls D are so proportioned as to equalize the horizont-al draft from the combustion-chambers through the kiln from all parts of the combustion-chamber.

'lhe chimneys E `arebuilt against the walls D, and

.have similar pigeon-holes to draw the draft into the chimneys. They are closed by dampers E', so that the draft may be taken out of any compartment or carried horizontally through as many as may be desired in a straight line, thereby equalizing the circulat-ion of heat throughout. A

I am aware that combustion-chambers have been arranged between the compartments of a continuous kiln built in the form of a circle or ellipse, andl therefore do not claim them broadly, but only in the described arrangement in relation to the compartments' and chimneys.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

4 l. The combination and arrangement of combustionchambers extending across the kiln, pigeon-holed walls D separating the combustion-chambers from the com- 'partments B and pigeon-holedV chimneys E, with damper-s E', arranged in relation to one another substantially as set forth.
